To provide for heat transmission of fluorescent tube accessory apparatus, a metal plate (16), for example of aluminum, is attached to the fixture structure which, otherwise, is entirely of plastic, having a base (3), a transparent closure cap (5) and an opaque cover cap (4). The caps (4) and (5), together with the base, define a chamber within which the lamp (2) is located, including the socket (6) thereof. Electrical accessory equipment (14) for the fluorescent lamp, for example starter, ballast and similar apparatus, is located against an internal support plate (15) which divides the chamber, the plate (15) having a reflective surface (22) facing the tube (2), and forming an attachment surface, at the same time, for the accessory apparatus (14). Plate (15) itself, is secured to support elements, such as posts and nipples (17, 20) extending from the support base interiorly of the chamber. All elements within the housing, thus, are double-insulated by the insulated housing structure itself.
